Itachi's personality is one of self - sacrifice and loyalty. If he is glaring at Shisui, it could be because he believes Shisui is straying from the path of loyalty to the clan or the village. His glare would be a cold and serious one, making Shisui aware of the gravity of the situation. Sakura, who has grown from a love - struck girl to a strong - willed kunoichi, would bring her determination to the table. Her glare might be accompanied by some verbal challenges, as she is not afraid to speak her mind. The combination of Itachi's silent but powerful glare and Sakura's more vocal and emotional one would create a very tense atmosphere around Shisui.
Shisui is known for his cheerful and friendly nature. He would likely be the one to break the ice with Sakura and make her feel welcome in the Anbu team. Itachi, on the other hand, is more reserved. He would respect Sakura's skills but might not be as openly friendly at first. Sakura, being strong - willed, would earn their respect over time with her determination and medical knowledge.
It could be that Shisui has been acting secretively lately. Itachi, being observant, and Sakura, who is also perceptive in her own way, notice this. They glare at him because they suspect he might be involved in something that could put the village at risk. Maybe he has been meeting with some suspicious characters. Itachi and Sakura's glares are a way of showing that they are on to him and that he should come clean about what he's been doing. As the story unfolds, Shisui might reveal that he was actually trying to protect the village in his own way, but his methods were misunderstood by Itachi and Sakura, leading to a lot of drama and tension in the fanfiction.
There could also be a more friendly and equal - footing relationship. They might bond over shared interests outside of combat, like a love for a certain type of flower in the village or a particular kind of food. This would bring them closer together on a personal level. Itachi, who is usually reserved, might open up more around Sakura and Shisui, and they could form a tight - knit group of friends who support each other through the difficulties in the shinobi world.
She could develop a more strategic mind. Shisui and Itachi are known for their intelligence in battle. Sakura would learn from them how to analyze situations better, plan ahead, and anticipate her opponents' moves. This would make her a more well - rounded ninja rather than just relying on her brute strength.
Sakura's evolution would be quite remarkable. She would start to think more like an Uchiha. Their way of analyzing situations and opponents would seep into her own mindset. This could make her more calculating and less impulsive in battles. Her physical strength, which she already has a good amount of, could be refined further with the training she gets from Shisui and Itachi. Her social standing in the village might also change as she is seen training with two of the most powerful and respected Uchiha. People would start to view her as a serious combatant as well as a healer, and she would have a greater influence on village matters related to security and combat strategy.
Sakura would likely be in awe of Itachi and Shisui's skills at first. Itachi, being the more reserved one, might be a bit distant but would gradually warm up to Sakura as he sees her determination. Shisui, on the other hand, would be more friendly and approachable. He might be the one to initiate conversations and break the ice between the three. They could have exchanges about their different ninja backgrounds.
Itachi and Shisui both being Uchiha have a deep bond based on their clan heritage. When Sakura enters the picture, she might initially feel like an outsider. But as they work together, Sakura's intelligence and combat skills earn her respect from the two Uchiha. Itachi might be initially cold towards Sakura but gradually come to respect her, while Shisui is more open - minded and quickly befriends her. They could form a triangle of mutual respect and support where they each bring different skills to the table.
Sakura's amusement could actually make Shisui more likely to continue annoying Itachi. Since she finds it funny, Shisui might see it as a sign that his actions are acceptable and entertaining. This could potentially strain the relationship between Shisui and Itachi further if Itachi doesn't like being the target of Shisui's annoyance.
Sakura's outgoing and determined personality would contrast with Itachi's more reserved and mysterious nature. Sakura would likely be the one to initiate conversations and try to draw Itachi out of his shell. Itachi, with his deep - thinking and often aloof manner, might initially seem uninterested, but over time, he could come to appreciate Sakura's straightforwardness and energy.
Sakura's character could develop in terms of her understanding of the ninja world. Itachi and Shisui have different outlooks compared to her. Through training with them, she might gain new perspectives on things like loyalty, sacrifice, and the greater good in the ninja world, which in turn shapes her character.
